Tóm tắt

PurposeThis study considers the natural convection in a horizontal annulus with constant heat flux on the inner cylinder, and investigates the transition of flows for various Prandtl numbers.Design/methodology/approachThe streamfunction‐vorticity equation and the energy equation governing the flow and temperature field are solved with finite difference method.FindingsResults are presented to show the transition of flow patterns with increase (or decrease) of the Rayleigh number, and a hysteresis phenomenon is observed.Originality/valueDual solutions are shown by using a numerical analysis in a horizontal annulus with constant heat flux on the inner wall.
